SNOW-PLOW.

SPECIFICATION forming part of Letters Patent No. 275,301, dated April 3,1883,

Application filed December 2, 1882.

' of which the following is a specification, reference being had thereinto the accompanying drawings.

My invention has relation to snow-plows for clearing railroad-tracks ofsnow; and its objeet is to provide a device that will either clear oftthe surface snow, or, should the snow drift or pack to a greater heightthan the train, then the machine tunnels a way through.

To these ends the novelty consists in the construction of the same, aswill be hereinafter more fully described, and particularly pointed outin the claims.

In the accompanying drawings similar letters of reference indicate likeparts of the invention.

Figure 1 is a side elevation of my improved plow. Fig. 2 is a frontelevation of the same. Fig. 3 is a top plan view of the plow with a Iportion of the upper shield removed, and Fig.

4 adetail view of one of the journals and bearings of the conveyers.

A is an ordinary plattorm-car,havin g wheels B is an engine and boilerof the usual construction, mounted upon the car A.

O O are arms projecting from the forward end of the car A,'aud to thesearms are secured the vertical hoods D D. Across the top of the verticalhoods D D is mounted a longitudinal hood, E.

F is the base of the vertical hoods D D, and it forms the lower bearingsof the conveyers G H, the shafts of which extend through so as toreceive the gear-wheels I J, (I not being sh0wn,) while the upper endsof said conveyers GH are journaled in the brackets ee, secured to theupper ends of the hoods D D and forming part of the cover h, and to thistop or cover It is secured the horizontal hood E. At both ends of thehood E is secured a bracket, 0, which forms the bearing for the shaft dof the conveyer d. The conveyers may be either of a single or doublescrew, and the vertical ones G H revolve from the center outward, whilethe horizontal conveyor d is provided (No model.)

with a right-and-left-hand screw, which accomplishes the sameresult-viz., carries the snow from the center of the track outward oneither side. Two vertical shafts, M N, are mounted in the rear of andparallel with the conveyers G H, and their lower ends are provided withgears m n, which mesh in the gears I J. The upper ends of these shaftsare provided with angle-gears m n, which mesh in similar gears, o 0,secured to the shaft 0, and on the center of this shaft is secured alarge gear-wheel, P, which is operated by the driving-gear R, located onthe crank-shaft S of the engine B. It will thus be seen that as theengine revolves the shaft 0 operates the angle-gears m n and 0 0simultaneously, and through the medium of the shafts M N and gears m nthe conveyers G H are rotated in unison. A gear, T, on the center of thehorizon tal conveyer d engages with the gear-Wheel P, so that the saidconveyor is also driven at the same time and by the same means as theother two, (ir H. Thus the operation of the engine causes the threeconveyers to revolve, and as the car is forced forward they pack thesnow on either side of the track.

Referring to Fig. 4, U is the shaft of one of the conveyers, which ispreferably made hollow to combine strength with lightness, and the endsare fitted with bearings V, having recess 12, and terminating in thejournal to.

X is a collar, and is rigidly secured to the frame Y. This collar entersthe recess a, and thus forms at once the support and bearing of theshaft U.

The front of the gear T on the conveyer d is protected by a cover, t,which prevents the snow from clogging the teeth of said gear.

The forward end, f, of the base F is inclined, so as to form a protectorfor the gears I J, and at the same time act as a shovel or scraper whilethe machine is being pushed forward.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent of the United States, is-.

l. The combination, with the conveyers G H, their hoods D D, and gears IJ ,of the gears on n, shafts M N, angle-gears m n, and the shaft 0,provided with the gears 0 0 and P, substantially as set forth.

2. The combination, with the conveyers G H, their hoods D D, andtheirgears, of the ICD presence of two witnesses, this 14th day ofNovember, 1882.
